vérnyomásesést

Vérnyomásesés, also known as hypotension, refers to a condition characterized by abnormally low blood pressure. Blood pressure is the force exerted by blood against the walls of the blood vessels, and it is typically measured in millimeters of mercury (mmHg). Normal blood pressure is generally considered to be below 120/80 mmHg, with the first number representing systolic pressure (the pressure when the heart beats) and the second number representing diastolic pressure (the pressure when the heart is at rest between beats).

Hypotension can be classified into several types based on the severity and underlying cause. Orthostatic hypotension, for example, occurs when a person's blood pressure drops significantly upon standing up, often due to a decrease in blood volume. Neurogenic hypotension is caused by damage to the autonomic nervous system, which regulates blood pressure. Hypovolemic hypotension results from a significant loss of blood volume, such as from severe bleeding or dehydration.

Symptoms of hypotension can include dizziness, lightheadedness, fainting, and in severe cases, loss of consciousness. Treatment depends on the underlying cause and may include fluid replacement, medication to increase blood pressure, or addressing the underlying condition.

Hypotension is a medical condition that requires prompt attention and treatment to prevent complications such as organ damage or shock. If you or someone else experiences symptoms of hypotension, it is important to seek medical attention immediately.
